Courtesy of Megacocorock, Rockman EXE: Phantom of Network has been uploaded to YouTube in its entirety. This is our best and most complete look at the game, which is no longer available in any form. The footage is in Japanese, though you can find a summation of the game's events here.
A spin-off from the EXE series, Phantom of Network was originally released in 2005 for mobile phones across eight chapters. The game features a unique scenario and new characters not seen in the GBA titles. The game was succeeded by Rockman EXE: Legend of Network in 2006. Footage from that game is few and far between, sadly. I'm hopeful Megacocorock pulls through on that front; he's quite resourceful.
Thanks for the heads up, Eric!
